An equal diameter tee means that both ends have the same diameter, and a reduced diameter tee is a branch pipe with different diameters. The expression method is as follows: For an equal diameter tee, such as “T3”, three ordinary means an equal diameter tee with an outside diameter of 3 inches. For a reduced tee, for example, “T4 x 4 x 3.5” means a reduced tee with a diameter of four inches and a diameter of 3.5 inches. The material is generally 10# 20# A3 Q235A 20g 20G 16Mn ASTM A234 ASTM A105 ASTM A403, tee, outer diameter range in 2.5 “-60”, from 26 “-60” for welding tee. The wall thickness is 28-60mm.
